JOHANN G. PETERSON, OF HARTFORD, CONNECTICUT.

HANDLE OR BUTTON.

To all whom it may concern Be it known that I, JOHANN Gr. PETERSON, a citizen of the United States. residing' at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Handles or Buttons, of which the following is a specification.

This invention relates to handles or buttons such as are used in connection with snap and other types of electric switches. It is customary to make the body of such a handle or button of some composition and to connect with said body a yoke which sustains certain spring mechanism. Ordinarily the old yoke or equivalent which is usually molded into the composition, fractures or breaks the same. while being cooled after baking. I provide a construction wherein this disadvantage is eliminated. In my case I mold as is common, into the composition a yoke, the branches of said yoke being resilient or flexible, so that said branches will contract and expand with the composition, the result being' that when the composition is cooling as set forth. the said branches will contract with the composition and thereby not break the same.

The foregoing is one of the principal` points of the present invention.

Another point is in the simplicity of cony struction and the ease with which the parts can be assembled.

In the drawings accompanying' and forming part of the present specification I have shown in det-ail one simple form of enibodiment of the invention which to enable those` skilled in the art to practice the same will be set forth fully in the following' description,`

while the novelty of the invention will be included in the claims succeeding said description. From this statement it will be clear that I do not restrictv myself to the showing made by said drawings and description; IE

may depart therefrom in several respects within the scope of my invention included? in the claims following' said description.

yoke 6. Referring' to the drawings: Figure l is a Speciication of Letters Patent.

Application filed September 22, 1911.

Patented Aug. 12,1913. Serial No. 650,745.

Figs. 7 and 8 are detail views of a spring' and washer.

Like characters refer t like part-s throughout the several figures.

In Figs. 1 and 2 of the drawings I have illustrated in full a button or handle involving my invention, the same being denoted in a general way by 2.and comprising a body or main portion 3 which is usually made of some composition as is usual and which has a cavity 4 in which certain part-s hereinafter described, are disposed. Among these inclosed parts is a yoke as 5 which is usually made from some metal, for example brass molded in said body. The yoke 5 as shown is o-f approximately rectangular construction, although this is not material, and is set into the cavity 4L, when the body 3 is in a plastic condition. and its side branches and head are embedded into the composition; that is to say the yoke 5 in its entirety is molded into said composition so that when the said composition body has been baked the yoke will be a permanent, rigid part thereof. When the composition body cools after baking it naturally contracts and to prevent the yoke from cracking' such body, the side branches of the yoke are made resilient or bendable so as to give with said body as the same cools.

Preferably but not necessarily fitted within the primary or main yoke 5 is a second- .ary or auxiliary yoke 6. the branches of which are bent toward each other near their free ends to produce the inwardly or downwardly converging angular portions 7 and straight port-ions 8, said straight port-ions being in parallelism. The angular portions 7 are slotted as at 9, and said slots 9 are adapted to receive lugs or projections 10 which may as shown. be punched from the side branches or legs of the yoke 5 and eX- tend inward therefrom. Said lugs or pro- `iections enter said slots 9 and engage the top walls thereofto thereby etl'ectually and substantially sustain the said secondary The legs or branches of the secondary or auxiliary yokek in addition to the bent portions also have inwardly extending feet l1 constituting together a support or carrier for a washer hereinafter described. As intimated the secondary yoke 6 fits wit-hin the primary yoke and to facilitate its introduction thereinto said secondary yoke G may have opposite slots as l2 extending` depthwise thereof and formed respectively in the branches and transverse portion thereof. lllere the slots not present, it would be dllicult to intrmluce the secondary yoke into the pri mary yoke in -view of the lack of resiliency at the junction between the branches and transverse portion of said secondary yoke. Owing to the presence of the slots, however, the secondary yoke can be readily inserted into the )rimary yoke during which motion the squared lugs or ears 1() will pass through the opposite slots 12. The secondary yoke is tit-ted into the primary yoke until the transverse portion of the latter abuts against the transverse portion of the former, and when this relation is nearly reached the branches or legs of the secondary yoke will be moved toward each other so that the lugs 10 will. enter the slots 9 a nd thereby also hold the same against lateral motion.

The numeral 13 represents a stem which as is customary is interiorly threaded to receive the spindle (not shown) of a snap switch or equivalent part so that the body 3 of said button will bear against the casing of said switch. The stem or nut 13 is provided withv a head 14 which may be of any suitable construction but which may illustrated consist of a plat-e perforated to receive the upper reduced portion of said stem, said reduced portion being riveted or headed over the plate or head so as to securely hold said plate or head in place. The said head or plate 14 is equipped with inwardly extending lugs 15, the side edges of which bear against the lateral walls of the cavity 11 to present an eifective bearing for said head and therefore for the stem 13, The transverse portions of the two yokes and 6, have perforations or holes 1G and 17 respectively to receive the upper reduced riveted or stak-ed 'portion ofthe stem 13.

Surrounding the stem 13 is a coiled spring 18 which constantly tends to retract said stem au d the outer end of which in the present case bears against the head 141:, while the inner end thereof bears against the washer 19 supported upon the feet 11 to which I have already referred.

The parts may be assembled as follows, it being understood that prior to assemblage the primary yoke is permanently connected with the composition body 3 and that the head 14 is connected .with the stem 1'3. The spring 18 placed around the stem 13 after which. the washer 19 is applied. The said stem with the spring and washer connected thereto is fitted within the secondary yoke 6 in such relation that the head le will bear against the transverse portion of said yoke 6, while the washer 19 will be supported upon the feet 11. These parts can then be connected with the primary yoke to accomplish which the yoke G will be thrust into the yoke 5, the slots 12 permitting the said yoke G to pass the lugs 10. Then the transverse portion of the yoke 6 is near the transverse portion of the yoke the washer 19 will be moved toward the head 14 thereby compressing the spring 1S and hence freely permitting the side branches of the yoke G to be moved toward each other and consequently causing the lugs to cooperate with the side branches of the secondary yoke as already set forth.

lt will be clear from the foregoing description that the composition body incloses a carrier which as described takes the .form of a yoke, this carrier constituting` a support for suitable locking mechanism for the button. The locking mechanism is frictional in type as will be understood. I might also indicate that while a composition body is greatly preferable, there may be cases where I can employ certain of the features already described in connection with a body which is not composition.

That I claim is:

1. A button, comprising a body having a cavity, a yoke fixed in said cavity, the side branches of said yoke having inwardly yextending lugs, and a second yoke disposed within the first yoke and supported by said lugs, said second yoke having slots to permit the second yoke to pass by said lugs when said second yoke is inserted in said lirst yoke.

2. A button comprising a body having a cavity, a yoke set in said cavity, the side branches thereof having invardly extending lugs, and a second yoke, the side branches of which are slotted to receive said lugs to thereby hold the second yoke in place, said second. yoke having elongated Vslots formed respectively in its side branches and transverse portion, said slots permitting the second yoke to pass by said lugs when said second yoke is inserted in said first yoke.

In testimony whereof I atliX my signature in presence of two witnesses.
